Safety circuit fault
• The inverter output is shut off when a safety circuit fault occurs.
• The inverter output is shut off if the either of the wire between S1 and SIC or S2 and SIC becomes non-
conductive while using the safety stop function.
• When the safety stop function is not used, the inverter output is shut off when the shorting wire between
terminals S1 and PC or across S2 and PC is disconnected.
• Settings of the switches (SW3 and SW4) for manufacturer setting may have been changed from the initial
settings.
• Check that the safety relay module or the connection has no fault when using the safety stop function.
• Check if the shorting wire between S1 and PC or between S2 and PC is disconnected when not using the safety
stop function.
• Check that the initial position of each switch was not changed.
• When using the safety stop function, check that wiring of terminal S1, S2 and SIC is correct and the safety stop
input signal source such as a safety relay module is operating properly. Refer to the Safety Stop Function
Instruction Manual for causes and countermeasures. (Contact your sales representative for the manual.)
• When the safety stop function is not used, short across terminals S1 and PC and across S2 and PC with
shorting wires. (Refer to
• Set each manufacturer setting switch to the initial position (OFF). (Refer to
switches.)

E.BE
Internal circuit fault
The inverter output is shut off when an internal circuit fault occurs.
Contact your sales representative.
E.OS
Overspeed occurrence
The inverter output is shut off when the motor speed exceeds the Pr.374 Overspeed detection level under PM
motor control. When Pr.374 = "9999 (initial value)", the inverter output is shut off when the motor speed exceeds
the "maximum motor frequency + 10 Hz".
• Check that the Pr.374 setting is correct.
• Set the Pr.374 correctly.
E.IAH
Abnormal internal temperature (IP55 compatible models only)
The inverter output is shut off when the inverter internal temperature reaches the specified value or higher.
• Check for too high surrounding air temperature.
• Check if the internal air circulation fan or the cooling fan stops due to a fault.
• Install an inverter suitable for the installation environment. (Refer to the Instruction Manual (Hardware).)
• Replace the internal air circulation fan or the cooling fan.
E.LCI
4 mA input fault
The inverter output is shut off when the analog input current is 2 mA or less for the time set in Pr.778 4 mA input
check filter. This function is available when Pr.573 4 mA input check selection = "2 or 3". (Refer to
This protective function is not available in the initial status.
• Check for a break in the wiring for the analog current input.
• Check that the Pr.778 setting is not too short.
• Check the wiring for the analog current input.
• Set the Pr.778 setting larger.
